Having never played the games myself I've been following the plot arc and I can see how this reflects back onm the Randian overtones. Also: most of the buildings seem to use props with hydrogen gas bags. Also the gameplay looks niiiiiice.

It looks really, really nice, but I wonder how all of those scripted events are going to work when you put a more "regular" player in front of it. Let's say, a bunnyhopping, drooling Counterstrike player.
